Water quality in the Clinch River is already impaired, and the river cannot withstand additional pollution. Since 2002, the Clinch River has been identified by the EPA as having unacceptably high levels of mercury, chlorane and other toxins. The river's condition is even worse after the coal ash disaster last year. Nevertheless, TDEC is not requiring TVA to limit the amount of mercury, selenium or other metals that will be discharged from its new scrubber system. Under the Clean Water Act TVA should be required to help restore water quality and at a minimum to install the best available treatment technology for its wastewater. Instead, TVA is dumping essentially untreated wastewater into the Clinch River.
